These documents as a worldwide announcement put a final end to the use of the notion of P-values in frequentist testing of statistical hypotheses. Statisticians might get the impression that abandoning P-values only affects Fisher s significance testing and not Neyman-Pearson s N-P hypothesis testing since these two theories of frequentist testing are different although they are put in a combined testing theory called Null Hypothesis Significance Testing NHST . Such an impression might be gained because the above documents were somewhat silent on N-P testing whose main messages are Don t say statistically significant and Abandon statistical significance . They do not specifically declare The final collapse of the Neyman-Pearson decision theoretic framework as previously presented in Hurlbert and Lombard 14 . Such an impression is dangerous as it might be thought that N-P testing is still valid because P-values are not used per se in it. 1 Corresponding author William M. Briggs Independent Researcher
